Description

Technical Field

[0001] The utility model relates to the technical field of balloon radon detectors, in particular to an automatic ventilation type balloon radon detector. Background Art

[0002] A balloon radon detector is an instrument used to measure radon gas concentration. Through specific technical means, the balloon radon detector can accurately measure the radon gas concentration in the environment, providing important data support for research and application in related fields. Patent application number CN201210337441.1 is an automatic ventilation balloon radon detector, which "comprises: a main unit, a radon gas collection chamber and a tripod. The main unit includes a radon gas sampling device, an automatic gas path switching device and a probe. The radon gas sampling device is used to collect and filter radon gas; the automatic gas path switching device is used to smoothly switch between gas paths when the balloon is pumped or exhausted, realizing a reversible airflow circuit. The present invention installs the radon sampling device and the probe in the same main unit of the automatic ventilation balloon radon detector. The step of manually replacing the gas circuit is omitted through the automatic gas circuit switching device, thereby avoiding gas leakage during the manual replacement process and improving the reliability of the balloon radon detector. The automatic ventilation balloon radon detector is installed on a tripod bracket, which is convenient for field use. During formal use, the gas drawn into the balloon contains impurities, which are easily blocked by the filter membrane and mixed with radon daughters, thereby affecting the test effect. Moreover, when the balloon is inflated, as the balloon gradually expands, the balloon is likely to fall off from the second delivery tube. Therefore, we propose an automatic ventilation balloon radon detector. Utility Model Content
